Abstract
A portable camera-phone (PH) has a strobe (10) consisting of LEDs (15 SIMILAR 17) emitting light with a determined quantity of light emission, as an auxiliary light source for image pick-up of an object (44) by a camera (9). In an image pick-up mode, the light emission quantity is adjusted repeatedly until a total exposure value (31) matches an optimal exposure value (141), based on a difference between a total exposure value of an image signal (34) output from the camera (9) with the light emission quantity determined last time and a total exposure value (31) when emission is OFF. Therefore, in the image pick-up mode, two reference values are used for determining the light emission quantity to have the total exposure value (31) match the optimal exposure value, and hence the light emission quantity can be determined with high accuracy. As a result, an optimal exposure level can be obtained with high accuracy.

95 pairs of picture signals of importing successively from CCD circuit 92 of exposure control part calculate exposure aggregate-value 31, output to control part 29.Specifically, stroboscope 10 is being carried out ON operation (lighting), stroboscope 10 is used as secondary light source under the occasion of photographing, to obtain the summation of photometric signal level from per 1 frame image signal of CCD circuit 92 inputs, accumulative total goes out this summation to multiframe.To be called exposure aggregate-value 31 as the resulting value of this result, control according to the principle that makes the luminous quantity of stroboscope 10 become optimum exposure value based on exposure aggregate-value 31.
On the other hand, stroboscope 10 is being carried out under the occasion that OFF operation (extinguishing) photographs, exposure control part 95 is obtained above-mentioned exposure aggregate-value equally, the optimum exposure value 141 that input is read from storer 14 by CPU15.95 pairs of CCD circuit 92 of exposure control part are provided for the control signal of exposure correction, so that exposure aggregate-value 31 reaches optimum exposure value 141.
The stroboscope control circuit 13 of Fig. 4 has the booster circuit 131 that is provided for driving stroboscope 10 voltages from battery BAT.
The optimum exposure value 141 that the CPU15 of control part 29 will be stored in storer 14 compares with the exposure aggregate-value of importing from exposure control part 95 31, result based on the comparison, control signal of will boosting 32 and ON/OFF signal 33 output to stroboscope control circuit 13, control the luminous action of stroboscope 10 by stroboscope control circuit 13.
Among Fig. 4, stroboscope 10 comprises LED (Light EmittingDiode) 15, the LED16 of output green light, the LED17 of output blue light and the conversion FET (Field Effect Transistor) 18～20 corresponding respectively with LED15～17 of output red light.The boost in voltage that booster circuit 131 will be supplied with from battery BAT based on the control signal 32 of boosting that provides from CPU15 is to the level that is used for driving LED 15～17.Booster circuit 131 has according to its output and reaches principle based on the stable current level of the control signal 32 of boosting, controls the function of constant-current circuit and electric current thereof.LED15～17 are connected in series with the output of booster circuit 131, and conversion is connected in parallel with LED15～17 are corresponding respectively with FET18～20, and ON/OFF control signal 33 is fed to FET18～20 grid separately from CPU15.Because by ON/OFF control signal 33, FET18～20 grid separately is by indivedual ON/OFF controls, thereby the LED that operated by ON of the grid of corresponding FET because two ends by short circuit, so be not supplied to the electric current from booster circuit 131, the LED that the grid that has only corresponding FET has been operated by OFF is forward supplied with from the electric current of booster circuit 131 and luminous.Therefore, passing through ON/OFF control signal 33, when FET18～20 were all operated by OFF, forward supplying electric current was also luminous by the while in LED15～17, irradiates the illumination light of white.
Can apply pulse-like voltage to FET18～20 respectively by ON/OFF control signal 33 in the limit in addition, the luminous quantity of LED15～17 is adjusted by changing its pulse width in the limit.
Be connected in series though suppose these 3 of LED15～17 here, also can be connected in parallel and constitute.
Fig. 6 represents a kind ofly to suppose that subject 44 is white, the illumination position level of the natural lights based on stroboscope 10 beyond luminous does not change in subject 44, when stroboscope 10 is luminous from camera 9 to subject 44 distance D (unit: * 10cm) with the illumination (unit: relation 1x) of subject 44.As shown in the figure, when distance D was dwindled, the illumination of subject 44 was very high, but along with the increase of distance D, the illumination of subject 44 just reduces.
In Fig. 7, suppose that subject 44 is white, illumination position level based on stroboscope 10 luminous natural lights does not in addition change in subject 44, the pass of exposure aggregate- value 31 and 44 the distance D from camera 9 to subject ties up under the occasion of stroboscope 10 luminous (ON) to be represented with solid line L1, extinguishes at stroboscope 10 under the occasion of (OFF) and represents with dotted line L2.The solid line L1 of Fig. 7 and the pass of dotted line L2 tie up to photography for all same in any one of feature pattern and mode standard.
Among Fig. 7, when stroboscope 10 luminous, distance D hour, exposure aggregate-value 31 is very big, but distance D is big more, exposure aggregate-value 31 is just more little.On the other hand, under the occasion that stroboscope 10 extinguishes, aggregate-value 31 does not all change no matter distance D how, is exposed.Therefore the difference and the distance D of the exposure aggregate-value of being represented by solid line L1 and dotted line L2 31 have corresponding relation.
Fig. 8 represents scope at the exposure aggregate-value 31 of the spatial brightness between camera 9 and the subject 44 with form.As shown in Figure 8, when the brightness between camera 9 and the subject 44 is when being used for the optimal brightness (as the brightness of target) of camera 9 photography, be expressed as 19～21 for exposure aggregate-value 31 by the picture signal of camera 9 photography outputs.When being not optimal brightness, exposure aggregate-value 31 adopts below 19～21 or above value.Therefore, be set at 19～21 as optimum exposure value 141 here.
Fig. 9 represents the content example of above table TB.In form TB shown in Figure 9, a plurality of poor DF and the luminous quantity LM corresponding have respectively been logined with difference DF.The difference of the exposure aggregate-value C of the exposure aggregate-value 31 of the exposure aggregate-value B of the exposure aggregate-value 31 of difference DF when representing with the time as stroboscope 100FF as stroboscope 100N.Luminous quantity LM is illustrated in when having detected corresponding poor DF, should be from the luminous quantity of stroboscope 10 outputs for making exposure aggregate-value 31 reach the position level of optimum exposure value 141.
Content according to the form TB of Fig. 9, DF is more little for difference, promptly the distance D between camera 9 and the subject 44 is big more as shown in Figure 7, increase the luminous quantity LM of stroboscope 10 more, avoiding under-exposed, otherwise difference DF is big more, i.e. distance D between camera 9 and the subject 44 more little (camera 9 is more near subject 44) as shown in Figure 7, reduce the luminous quantity of stroboscope 10 more, to avoid overexposure.Therefore in Fig. 9, when the DF that is on duty was minimum (0～10), luminous quantity LM was set to MAX142, and when the DF that is on duty was maximum (66～70), luminous quantity LM was set to minimum.
Figure 10 is by the ON/OFF control sequence through the following stroboscope 10 of presentation graphs 1 order of coming of time T.Next, with reference to the order of Figure 10, action is explained by the flow process of Fig. 1.
At first, operator scheme changer lever 11 is set to any one photograph mode (step S (following simple for S) 1) of mode standard and feature pattern.
Next, because the user presses luminous ON/OFF key 5 (S 2), thereby CPU15 begins exposure adjustment when the inferior ordered pair stroboscope 10 according to Figure 10 carries out ON/OFF control.Specifically, at first, export boost control signal 32 and ON/OFF signal 33, at the timing T1 of Figure 10 stroboscope 10 is set at OFF, so that its not luminous (S2).Under this state, because subject 44 photographed by camera 9, thereby CPU15 input image data 34 and exposure aggregate-value 31 (S3, S4).Be made as exposure aggregate-value A with the exposure aggregate-value of being imported 31 this moment.
CPU15 reads optimum exposure value 141 from storer 14, and optimum exposure value 141 and the exposure aggregate-value A that is read compared (S5).If result relatively is exposure aggregate-value A 〉=optimum exposure value 141, because even stroboscope 10 is not luminous, also can obtain enough exposure values, thereby CPU15 to judge view data 34 be to store the data of storage part 27 into, and judge whether the user has carried out ON operation (S18) to shutter key 6.CPU15 deposits storage part 27 (S19) determining shutter key 6 by after the ON operation with the view data 34 that imported this moment.After this, judge whether photograph mode ends (S20).End (is YES (being) at S20) if determine, finish a series of processing (EXIT), otherwise (is NO (denying) at S20) returns the processing of S 3, imports next view data 34, repeats later processing equally.
Like this, under photograph mode, at first detect the exposure value not make when stroboscope 10 is luminous to obtain enough photographies, if enough, then can not make stroboscope 10 luminous photographies, thereby can avoid the invalid power consumption of relevant battery BAT.
On the other hand, when CPU15 determines exposure aggregate-value A＜optimum exposure value 141, promptly determine exposure when not enough, change (activations) is used for deciding based on the difference of exposure aggregate-value 31 that calculates and the exposure aggregate-value 31 that calculates luminous quantity under non-luminous state under the luminous state of stroboscope 10 the later processing of S6 over to.
At first, the luminous quantity with stroboscope 10 is set to MAX value 142 (S6).Specifically, read MAX value 142, generate boost control signal 32 and ON/OFF signal 33 under the MAX value 142 of being read, and output to stroboscope control circuit 13 from storer 14.At the timing T2 of Figure 10, stroboscope 10 according to ON/OFF signal 33, comes luminous (S 7) with the current potential under the MAX value 142 by stroboscope control circuit 13 like this.
The view data 34 of CPU15 input this moment, the exposure aggregate-value 31 of relevant this view data 34 (S8, S9).Here the exposure aggregate-value of being imported 31 is made as exposure aggregate-value B.
The CPU15 aggregate-value B that will expose compares (S10) with the optimum exposure value 141 read from storer 14.If result relatively determines exposure aggregate-value B≤optimum exposure value 141, judge that whether shutter key 6 is by ON operation (S21).CPU15 deposits storage part 27 (S22) determining shutter key 6 by after the ON operation with the view data of being imported 34, judges whether photograph mode ends (S23).End (is YES (being) at S23) if determine photograph mode, finish a series of processing (EXI T), otherwise (is NO (denying) at S23) imports next view data 34 (S8), repeats later processing equally.
Therefore, luminous by MAX value 142 because during the ON of stroboscope 10 after OFF, thereby such as in the photography in the dark, can obtain the brightness that suits rapidly, i.e. Shi Yi exposure level.
On the other hand, when CPU15 determines exposure aggregate-value B＞optimum exposure value 141, make stroboscope 10 luminous if promptly determine by the position level under the MAX value 142, with over-exposed, present unfavorable photography state, then according to eliminating this over-exposed state, the principle that reaches suitable exposure value is carried out following processing.
Promptly, the CPU15 aggregate-value B that will expose deposits the scratchpad area (SPA) TE (S11) of storer 14, according to timing T3 at Figure 10, principle according to the luminous OFF of the carrying out operation (extinguishing) of boost control signal 32 and 33 pairs of stroboscopes 10 of ON/OFF signal is controlled (S12), thereafter, the exposure aggregate-value 31 of input image data 34, relevant view data 34 (S13, S14).The exposure aggregate-value 31 of this input is made as exposure aggregate-value C.
The CPU15 aggregate-value C that will expose compares (S15) with the optimum exposure value 141 read from storer 14, and the result if determine exposure aggregate-value C 〉=optimum exposure value 141, returns the processing of S3 as a comparison, repeats later processing equally.
On the other hand, according to comparative result, if determine exposure aggregate-value C＜optimum exposure value 141, then be judged as after the luminous OFF of carrying out operation stroboscope 10, can not obtain enough exposure values, under-exposure, decision is corresponding to the luminous quantity based on the stroboscope 10 of stroboscope 10 non-luminous exposure values, and control signal 32 and ON/OFF signal 33 are controlled the luminous of stroboscope 10 by boosting.Specifically, the exposure aggregate-value C's of the exposure when CPU15 calculates and as the exposure aggregate-value B that reads from scratchpad area (SPA) TE of the exposure when MAX value 142 times has been carried out the ON operation to stroboscope 10 and expression stroboscope 10 carried out that OFF operates is poor, come retrieval table TB based on this difference, the stroboscope luminous quantity LM that decision is corresponding also reads (S17).Therefore, the decision of stroboscope luminous quantity LM is the simple process of a kind of retrieval table TB, thereby can determine rapidly and simply.
Carry out luminous principle according to stroboscope 10 by the stroboscope luminous quantity LM that is read, generate boost control signal 32 and boost ON/OFF signal 33 and output according to stroboscope luminous quantity LM.Therefore, at the timing T4 of Figure 10, stroboscope 10 comes luminous (S7) by the position level of the luminous quantity LM corresponding with difference DF.Below same re-treatment.
Like this, after stroboscope 10 being carried out ON operation and making it luminous, because of the over-exposed OFF that carries out operates, only under natural light under the under-exposed occasion, exposure aggregate-value C's when exposure aggregate-value B during based on ON and OFF is poor, decides the luminous quantity LM of stroboscope 10 according to the principle that makes exposure aggregate-value 31 meet optimum exposure value 141.Since this decision during with reference to ON exposure aggregate-value B and these 2 values of exposure aggregate-value C during OFF carry out, thereby compare with the occasion that 1 value of reference determines, can more correctly determine to become the luminous quantity LM of optimum exposure value 141.In addition because these 2 exposure aggregate-value B are relative (being in antagonistic relations) values of so-called stroboscope 10 luminances and non-luminance exposure aggregate-value separately with C, thereby with compare such as the occasion that adopts 2 exposure aggregate-values that under 2 exposure aggregate-values that obtain under the luminance of stroboscope 10 or non-luminance, obtain at stroboscope 10, can determine luminous quantity more accurately.
As shown in Figure 7, the difference of exposure aggregate-value C when exposure aggregate-value B during owing to ON and OFF changes corresponding to the distance D of camera 9 with subject 44, thereby can become the decision of the luminous quantity LM of optimum exposure value 141 corresponding to distance D by the luminous quantity LM that decides stroboscope 10 based on this difference.
When 9 pairs of subjects of camera 44 of the portable telephone PH that utilizes the band camera are photographed, the limit portable telephone PH of hand moving belt camera, monitoring picture is confirmed on the limit on LCD3, simultaneously to subject 44 photographies.Therefore, even is the occasion that mode standard is photographed in when photography from the feature mode switch, perhaps in opposite occasion, subject 44 changes all the time with the distance of camera 9, the also change of limit tracking range D as mentioned above, the limit is adjusted according to the principle that the luminous quantity that makes stroboscope 10 reaches optimum exposure value.
Owing in photograph mode, adjust luminous quantity, continue to be in the optimum exposure state, thereby can know the operation timing of shutter key 6 like this by the monitoring picture of LCD3.Can judge rapidly also whether focus produces deviation, the user can suitably carry out the mode switch between mode standard and the feature pattern.
Here, the photography under the AD HOC is done to record and narrate.The portable telephone PH of the band camera of Fig. 3 has the function that is connected with not shown the Internet by the communication by radio section 22 and antenna 21.For being connected, need obtain the information of relevant URL (Uniform Resource Locators) with the Internet.Under present embodiment, can obtain this URL information by conduct being resolved by the view data 34 of the bar code of the subject 44 of feature pattern photography by CPU15.
Under the occasion to the bar code photography under the feature pattern, though camera 9 (the portable telephone PH of band camera) is near bar code itself, space deepening between bar code and the camera 9, but can decide the luminous quantity LM of stroboscope 10 according to the principle that reaches optimum exposure value.Like this, the focusing deviation also can be revised rapidly.Consequently, can correctly read URL information from the view data 34 of bar code.
Though in the present embodiment, optimum exposure value 141 as fixed value, also can be changed arbitrarily.Such as, the user has the exposure level of hope not according to the best, but by the position level that becomes brighter image or become the demand of the position level of darker image to subject 44 photographies, thereby be corresponding with this demand, can carry out variable setting to optimum exposure value 141 according to user's request.
Though in the present embodiment, suppose that stroboscope 10 has adopted LED, also can adopt light source in addition.
Though in addition in the present embodiment, stroboscope 10 sends redness, green, blue this 3 look simultaneously, and luminous as so-called white, illuminant colour can be random colour.
Though in the present embodiment, suppose the band camera portable telephone PH be shaped as shown in Figure 2ly, be not to be defined in this shape.
In addition in the present embodiment, the example of the exposure adjustment function that will adopt stroboscope having been carried the portable telephone PH of band camera is described, but as the portable equipment that is carried not is to be defined in this, such as being the digital camera that has adopted stroboscope, the portable type information terminal that has the camera that has adopted stroboscope etc. yet.
